From Embryology
Stage Mouse Age Features
Embryonic E9 to E11.5 lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs
Pseudoglandular E11.5 to E16.5 conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching
Canalicular E16.5 to E17.5 bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development
Saccular E17.5 to PN5 alveolar ducts and air sacs are developed
Alveolar PN5 to PN28 secondary septation occurs, marked increase of the number and size of capillaries and alveoli
